Architectural Evolution of Monitor and Control Systems - Issues and Challenges

Abstract

Large-scale Complex Critical Infrastructures (LCCIs), such as power grids and transport infrastructures (e.g., network of airports and seaports), play a key role into several fundamental human activities, and represent the next generation of Monitor and Control Systems. They make extensive usage of Information and Communications Technology (e.g., computing systems, communication networks, and sensing hardware) for providing support for advanced monitoring and control facilities. However, solutions currently adopted in the field exhibit several inefficiencies when applied to LCCI. On the contrary, Distributed Event Based Systems (DEBS) seem promising solutions due to their intrinsic decoupling properties that enforce strong scalability degrees. However, they also present some open issues when dealing with the challenges imposed by LCCIs. This paper provides an introduction on LCCIs, a presentation of their challenges, and an analysis on the adoption of DEBS for LCCIs

Information theoretic‐based detection and removal of slander and/or false‐praise attacks for robust trust management with Dempster‐Shafer combination of linguistic fuzzy terms

“…Such a figure can represent a large-scale critical infrastructure made of multiple systems glued together by the middleware, 20 or even a set of cloud platforms, each with a proper set of physical and virtual machines, that are integrated so as to realize a federated cloud. Such a figure can represent a large-scale critical infrastructure made of multiple systems glued together by the middleware, 20 or even a set of cloud platforms, each with a proper set of physical and virtual machines, that are integrated so as to realize a federated cloud.…”

“…A schematic overview of the reputation‐based trust estimation for federated architectures implementing an SoS concept is depicted by Figure , where there is an integration and federation middleware acting as a communication bus among the applications hosted by a set of geographically sparse computing machines. Such a figure can represent a large‐scale critical infrastructure made of multiple systems glued together by the middleware, or even a set of cloud platforms, each with a proper set of physical and virtual machines, that are integrated so as to realize a federated cloud . The applications hosted in the computed nodes represented within Figure directly interact among themselves (red arrows in the figure) by mutually exchanging data, and/or requesting certain functionalities.…”

Layered multicast for reliable event notification over large-scale networks

“…Concrete examples, just to cite some of them, are represented by the use of such services for the federation of cloud infrastructures [20] , the realization of the so called large-scale complex critical infrastructures [6] , the integration of health information systems at a national or trans-national scale [17,36] , building large-scale scientific applications [12] , the exchange of massive data for homeland security [44] , or the Intelligent Business Information Management [43] .…”

Achieving Reliable and Timely Event Dissemination over WAN

“…Publish/Subscribe services are facing a growing interest in designing innovative critical infrastructures, named Large-scale Complex Critical Infrastructures (LCCIs), which consist of federating geographically-distributed systems by means of wide-area networks [1]. The reason behind this interest is the intrinsic decoupling properties offered by such middleware, which are suitable for satisfying the scalability requirements exhibited by large-scale infrastructures.…”
